PERCOLATOR FOR COFFEE-URNS.

To all whom it may concern:

Be it known that I, JOHN D. I-IoUoK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Percolators for Coffee-Urns; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in percolators forcoffee urns and comprises a simple and eflicient device of this naturehaving various combinations and arrangements of parts which will be'hereinafter fully described and then specifically defined in theappended claims.

I illustrate my invention in the accompanying drawings, in which Figurel is a sectional view showing the application of my invention to an urn.Fig. 2 is a perspective view of a percolator by itself showing rings fordistending the top and bottom thereof. Fig. 3 is a sectional viewvertically through the percolator and rings, and Fig. 4 is a detail Viewof the percolator with the rings removed.

Reference now being had to the details of the drawings by letter, Adesignates an urn having an annular flange B at the inner surfacethereof adapted to support the percolator. The percolator consists of abag D, the circumferential wall of which is made of a fine stout clothor fabric, while the bottom E is made of a cloth of coarser weave thanthe circumferential wall. Said bag has its upper end outwardly flaredand turned into a partial roll forming an annular groove H, shownclearly in Fig. 4 of the drawings, and adapted to receive a ring K, asillustrated in Figs. 2 and 3. The lower part of the bag Specification ofLetters Patent.

flares outwardly, and N is a second ring of smaller diameter than thering'H and is adapted to hold the bottom of the bag, which is formed ofa coarser weave cloth than the side, taut. It will be noted that, whenthe percolator is adjusted in position, the upper ring II will rest uponthe flange B of the percolator and form secure means for supporting thebag.

I have found from experimenting that, by having a heavy, finely wovencircumferential wall to the bag, it will cause the coffee to spread outover the flat taut bottom, which latter is made of a coarse weave andthus allowing hot water to pass readily through the coffee and not runout over the sides. Said rings, it will be noted, are not fastened inany way to the bag but may be easily removed when desired.

What I claim to be new is A percolator for urns comprising, incombination with the urn having a conical shaped shell mounted thereinwith a laterally extending flange at its upper end bearing against theend wall of the urn, the inner surface of the urn having an annularshoulder near its top, a ring having a circumferential flange restingupon said shoulder and an inwardly turned flange at its lower endadapted to rest upon the flange at the upper end of said shell, apercolator bag, a ring engaging the upper marginal edge thereof andresting upon said inwardly turned flange, the bottom of the percolatorflaring, a ring holding the same taut, the bottom of the percolatorbeing of a coarser mesh material and the surrounding wall of a finemesh.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses.
